Isopropyl palmitate | CAS No. 142-91-6

Q: What is Isopropyl palmitate (CAS: 142-91-6)?

Isopropyl palmitate (CAS: 142-91-6) is a colorless, oily liquid ester derived from palmitic acid and isopropanol. It has a molecular formula of C19H38O2 and is commonly used as a skin emollient and solvent in cosmetic and pharmaceutical products. The compound is non-irritating, odorless, and exhibits low water solubility, making it ideal for applications requiring smooth texture and stability.

Q: What are the main uses of Isopropyl palmitate (CAS: 142-91-6)?

Isopropyl palmitate (CAS: 142-91-6) is widely used in skincare formulations as an emollient, fragrance carrier, and texture modifier. It also serves as a penetration enhancer in pharmaceuticals, a lubricant in industrial applications, and a component in some food products as a flavoring agent. Additionally, it is utilized in research for studying lipid interactions and formulation development.

Q: Is Isopropyl palmitate (CAS: 142-91-6) safe?

Isopropyl palmitate (CAS: 142-91-6) is generally considered safe when used in compliance with regulatory guidelines. It has low toxicity and is approved by the FDA and EPA for cosmetic and pharmaceutical use. However, direct skin contact may cause mild irritation in some cases, so proper handling, such as using gloves and ensuring ventilation, is recommended. Always follow safety data sheet (SDS) instructions for safe exposure limits.

Q: How should Isopropyl palmitate (CAS: 142-91-6) be stored?

Isopropyl palmitate (CAS: 142-91-6) should be stored in sealed, airtight containers in a cool, dry place away from direct light. It is stable under normal storage conditions but should be protected from high temperatures and moisture to prevent degradation. Maintain storage temperatures below 25°C and ensure humidity levels are controlled for optimal product longevity.
